Abstract:
Objective To evaluate the disc herniation by the technique of MRI FFE.Methods T1WI,T2WI and FFE sequences were performed in 40 cases with cervical and lumbar vertebra disc herniation using 1.0T MRI equipment on sagittal and transection sections.The showing rate of disc fibrous circle rupture,extrusion directon and nerve-root pressure in disc herniation on FFE,T1WI and T2WI sequences were comparated emphasisly.Resilts In the observation of cervical nucleus pulpous prolapse and free disc fragment showing fibrous circle rupture,extrusion direction and nerve-root pressure in cervical region,and showing fibrous cicrcle rupture in lumbar region,the FFE was better than T1WI,T2WI.In judging extrusion direction and nerve-root pressure,the FFE sequence was better than T2WI and T1WI respectively.Conclusion MRI FFE can improve the diagnostic ratio of the extrusion of nucleus pulpous,annular bulge as well as free disc fragment.
